The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom. Isaac Asimov - Max Tegmark

If we don't know what we want we're less likely to get it.

We don't know for sure that the Schrödinger equation is actually that accurate a description of nature either. That's why it's so exciting to see what's going to happen with the quantum computer efforts... Will they ultimately fail because physics isn't fully described by the Schrödinger equation, or will they actually succeed... This is where ultimately our experimental friends will... give us crucial insights...

Aristarchos of Samos... was able to use to figure out... the distance between the Earth and the Sun. His conclusion... the Sun was about twenty times farther... than the Moon and therefore twenty times bigger than the Moon. In other words, the Sun was... over five times bigger than the Earth in diameter. This insight prompted Aristarchos to propose the heliocentric hypothesis long before Nicolaus Copernicus... It turned out to be quite difficult to tell precisely when the Moon was 50% illuminated, and the correct Sun-Moon angle... isn't 87 degrees but about 89.85 degrees... This makes... the Sun... almost twenty times further away... and about 109 times larger than the Earth... [T]his wasn't corrected until almost two thousand years later, so when Copernicus came along... the overall scale of his Solar System model was about twenty times too small...
